It is funny you should bring this up. As a mental exercise at times I
have thought how great it would be to go back and purchase certain
things that later became valuable. The one sticking problem is what do
you use for currency? You walk in to a bank to buy all those silver $1
coins using what is now almost a worthless $1. What do you hand them?
A new bill? Before your trip do you go out and buy as many FRN's from
the era you are traveling to? Depending on the era, those FRN's might
cost you as much as the coins you are trying to purchase.
As for other commodities, taking $900 an ounce gold back to the 1920's
at $35 and ounce would not work. Silver? Diamonds? The trick is to find
something that was more valuable in the past than it is now. A rather
difficult proposition. The only thing I have managed to come up with is
CPU chips and that will only get you to perhaps the 1980's. Hoard up a
bunch of used Pentium chips that are almost worthless now and take them
back to a month after their release and sell them. Do the same with
other variants and you can probably get a small fortune.
